It is used to alert you to potential physical injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. Operator Safety Protection WARNING Check that the Cutter is free of any abnormalities before using it. If there is chipping, significant wear, or other Cutter abnormality, there is the risk that it may be damaged and pieces may fly off during use. DO NOT touch the Cutter while it is rotating. Before rotating the Cutter, be sure to close the equipment door and take other necessary action. If oscillation or other abnormality occurs during use, discontinue use immediately. This is dangerous and there is the risk of Cutter falling off, breaking, or rupturing. Use protective gloves and other protective gear when touching the Cutter. There is a risk of injury and burns if the Cutter blade is touched with bare hands. Use of protective equipment Wear personal protective gear including goggles, masks, gloves, and earmuffs to prevent loss of sight, injury, or lung damage caused by damaged parts flying off the product. Wear clothing with long sleeves or other clothing that does not expose the skin, and fasten the cuffs and hems tightly. Precaution regarding cutting particles Fragments, cutting particles, and other substances generated during work will be scattered into the surrounding area. Be sure to use a dust collector or other means to collect them. Attention to the work area Install an enclosure so that persons other than the operator do not enter the work area, and ensure that all persons, if any, in the work area are wearing protective equipment. In particular be careful that children do not enter the work area. Keep the floor of the work area clean at all times to prevent the risk of slipping or tripping on dust, cutting particles, oil, water, or other substance.

Also be sure to enact fire prevention measures. 1 Page 1/30

3 SAFETY PRECAUTIONS Be sure to read. Setup and installation WARNING Be sure to check the dimensions prior to use. There is the risk of injury or burns if a person touches the Cutter blade directly with a hand. During use, the workpiece must be fastened securely to the machine tool or jig so that it does not move. If the workpiece moves during machining, there is the risk of damage to the Cutter or flying pieces of the workpiece. Before performing actual machining, use no-load running, machining simulation software, or other means to check the operation until it is confirmed that there are no errors in the Path. If there is an error in the Path, there is the risk of damage to the Cutter or workpiece. Before use, the point group data of the Path set the tool geometry offset using the axis center and tip of the Cutter. Use of a Path with tool geometry offset that does not use the axis center and tip of the Cutter is dangerous and there is the risk of Cutter breakage or machine accident. Perform positioning correctly to minimize the accumulative error in the position and size of each hole. There is the risk of breakage caused by interference with the Cutter head. In particular, set tool geometry offset using the center and tip of the Cutter. If you continue to use the product exceeding the accumulative error allowance, the Cutter may break. When installing onto the milling holder, make the runout 0.01 mm or less. If runout is large when the tool is installed, there is the risk of chipping and breakage when the tool starts rotating and when it cuts into the workpiece. Use the incremental command mode to use the point group data. Use point group data with the correct command type for the product type you are using. Unexpected operation of the machine may result in damage to the product, jig, and machine. NOTICE If you continue to use the product exceeding the accumulative error allowance, there may be a deterioration in the quality of the edge after removing burrs. 2 Page 2/30

4 SAFETY PRECAUTIONS Be sure to read. WARNING Select and use a coolant/cutting fluid that is suitable for the purpose. Depending on the type of coolant/cutting fluid, there is the risk of fire caused by overheating, sparks, or other problem.if heating or sparks are expected, be sure to implement fire prevention measures. Pre-work inspection NOTICE Check in advance that the Cutter shank and milling holder do not contact the workpiece or other objects. Select and install a Cutter with consideration for the movement path of this product. If the product will be used for wet machining, adjust so that the coolant/cutting fluid properly contacts the blade tip. If the amount of coolant/cutting fluid contacting the tip is not sufficient, the blade tip temperature will rise and its tool life may be shortened. Suppress the size of burrs occurring at the previous machining process as small as possible. If the burr root thickness from the previous process is larger than the depth of cut set in the Path, there is the risk that burrs will not be fully removed. Precautions for use WARNING DO NOT use at the excessive rotational speed. The rotational speed for this product varies depending on the Cutter size. If used at excessive rotational speed, there is the risk of Cutter chipping or breakage. DO NOT use the product rotating in the reverse direction. This product is ordinarily used rotating clockwise. Using the product rotating counterclockwise is dangerous and the Cutter is certain to be damaged when it cuts into the workpiece. DO NOT use this product with manual tools or similar equipment. This product is a dedicated tool for use only with numerical control processing machines. Using the product with a manual tool or similar equipment is dangerous and there is the risk of injury resulting from damage to the Cutter. DO NOT use this product for any purpose other than deburring or chamfering. This product was designed for workpiece deburring and chamfering. If it is used for curved face machining or other machining which it was not designed for, there is the risk that the Cutter will be unable to withstand the load and will break. NOTICE If the location of deburring has an intermittent shape, check the condition of the Cutter blade carefully. If there is a notch or other intermittent shape at the location of deburring, chipping of the blade will be more likely, and depending on the depth of cut the Cutter tool life may be significantly reduced. Regular maintenance When changing the Cutter, remove any dirt from the tool holder grip and Cutter shank, and keep these parts clean. 3 Page 3/30

5 Introduction Product overview The XEBEC Back Burr Cutter and XEBEC Path for Back Burr Cutter are a dedicated cutter and dedicated path specifically for the purpose of removing burrs at crossing edges that are produced by hole drilling. Notes when using the XEBEC Path for Back Burr Cutter The XEBEC Path for Back Burr Cutter may be used only by those customers who at the time of purchase agreed to the terms of use. These terms prohibit use with any equipment other than the XEBEC Back Burr Cutter, and also prohibit the transfer or provision of the generated paths to another company. Be sure to observe these terms of use. Product contents This product is composed of the following parts. Please check the product contents at the time of purchase.

6 Introduction (continued) Features XEBEC Back Burr Cutter Use of micro-grain cemented carbide Higher cutting ability and longer tool life Use of highly heat resistant AlTiCrN coating Allows the product to be used with aluminum and other non-ferrous metals, as well as titanium, inconel, and other hard-to-cut material. Optimal blade shape for deburring A helical Cutter is used for better cutting performance and fewer secondary burrs. Long under-head length The regular type has an under-head length that is 5 times the spherical diameter, while the straight type has a length that is 15 times. This allows back deburring of deep holes. XEBEC Back Burr Path Generation of the optimal machining paths for deburring Machining with the optimal cutting for 3D free curved surface edges suppresses the occurrence of secondary burrs. The best depth of cut for the designated cutting width is calculated to produce an uniform machining shape. Capable of deburring a variety of deburring holes including orthogonal cross holes, off-center cross holes, and flat surface cross holes. With orthogonal cross holes and off-center cross holes (examples: P6, Figure 2), a Path is generated that can deburr cross holes at the parts indicated by the red lines, which were previously difficult to deburr. Longer tool life for lower running costs The optimal machining path reduces the amount of cutting, reducing wear caused by heating. Machining is performed while changing the point that contacts the workpiece, extending the Cutter tool life. Fast deburring with contour machining operation Can complete deburring in 1/5-1/10 the machining time required with a spring-type deburring tool. Can perform deburring at multiple locations with a single direction approach. Thanks to the long under-head length, a Path is generated which allows 1 Cutter to deburr multiple locations with an approach from a single direction. 5 Page 5/30

7 Introduction (continued) Supported machine tools When machining with a XEBEC Path for Back Burr Cutter for XZY axes, use an NC lathe that has milling functionality that enables simultaneous 3 axis control of the XZY axes. When machining with a XEBEC Path for Back Burr Cutter for XZC axes, use an NC lathe that has milling functionality that enables simultaneous 3 axis control of the XZC axes and that permits commands for polar coordinate interpolation functionality. Axial orientations compatible with XEBEC Back Burr Paths As indicated in Figure 1, axis configuration are required that are able to insert the Cutter in the X direction for XZY axes and in the Z direction for XZC axes. Cutter insertion direction for the XZY axes Deburring locations The red lines in Figures 2 is example of the deburring locations Cross hole A hole that crosses the main bore. Main bore A hole drilled from the end face of a workpiece. (A hole whose hole axis is parallel to the Z-axis.) Outer diameter Outer diameter of the workpiece whose axis center is Z-axis and its inner diameter. Figure 2 [Note] Depending on the combination of holes, there is the possibility that a Path cannot be generated. For the restricting conditions and precautions, check the Path Code Sheet that was provided at the time of the order. Figure 1-1 Figure 1-2 Cutter insertion direction for the XZC axes 6 Page 6/30

If machining is performed using the wrong size Cutter, considering the interference between the tool, workpiece, jig, and chuck, there is a risk of damage to the product, jig, and machine, so make sure you check the dimensions before use. 2. When installing the Cutter on a milling holder, set the appropriate projection for the location to be machined. 3. Secure the Cutter firmly in the milling holder so that it does not move during use. 4. After attaching the Cutter to the milling holder, confirm that the runout of the Cutter is 0.01 mm or less. 5. Point group data is calculated using the center and tip of the Cutter, so tool geometry offset should be set on the center and tip of the Cutter. (Refer to "Set position for tool geometry offset" on page 11) 6. There is a danger that there will be interference with the Cutter head, so care should be taken when positioning so that there is minimal accumulative error with the main bore and outer diameter, and the position and hole diameter of the cross hole. 7 Page 7/30

To improve the machining conditions, take steps such as adjusting the rotational speed and feedrate, or changing to a Path with a different deburring amount. If oscillation or noise occurs, or if the rotational speed or feedrate does not satisfy the value in the standard machining conditions table, lower the rotational speed and feedrate by the same proportional amount. When machining with a XEBEC Back Burr Path for XZC axes, pay attention to the units used in commands for feedrate to be used. As the machining with the XZC axes is done in the polar coordinate interpolation mode, feedrate command includes feedrate of both the rotating axis and the straight axis ( /min). Convert feedrate of the straight axis (mm/min) to a feedrate that includes the rotating axis and the straight axis ( /min). Depending on the type of cross hole, care needs to be taken with the setting conditions, so refer to the pages for start points for the type of intersecting edge used in "Machining edge variation" (page 14). It is possible to reduce machining shape error by using functions such as advanced preview control. POINT Setting processing conditions Secondary burrs may occur depending on the state of the intersecting edges. Keep the tool projection as short as possible, set feedrate to 50% of the standard condition, and try starting from a small deburring amount. 8 Page 8/30

12 Product specifications (continued) Set position for tool geometry offset The point group data for the XEBEC Back Burr Path is calculated using the center and tip of the tool. Set tool geometry offset for the XEBEC Back Burr Cutter using the center and tip of the Cutter so that it is as shown on the OK side in Figure 6. Accumulative error The 5 deburring amounts (Figure 7: Surface width after burr removal by the Cutter) that are provided with XEBEC Back Burr Path must be selected with consideration for the accumulative error from previous machining. Use a deburring amount Path that is suitable for the processing accuracy of the workpiece hole diameter, hole position, and other dimensions. Figure 7 If the Cutter does not contact the edge due to machining variation of hole position or excessive hole size, check using a Path with a larger deburring amount. If the deburring amount is too large because the actual dimension (diameter) of the machined hole is small, check using a Path with a smaller deburring amount. Product code Cutter diameter Dc (mm) NOTICE Set the Path point group data using the tip of the Cutter. Use of a path with tool length offset that does not use the tip of the Cutter is dangerous and there is the risk of Cutter breakage or machine accident.
